Harmann IZOBOX

Radial duct fan in a rectangular housing with sound insulation. The casing is made of galvanized sheet steel with a hinged service cover (fixed with quick clamping clamps), connecting sockets and a junction box. IZOBOX is a model with a layer of sound insulation reduced by approx. 10% while maintaining the properties of full insulation. The sound absorbing material is a 35 mm layer of mineral wool meeting fire protection requirements for class A1 – non-flammable.

The dynamically balanced impeller type F is an integral part of the engine (so-called motor with a rotating casing).

The drive in the IZOBOX model is realized by a single-phase asynchronous 230V, 50Hz electric motor with integrated thermal protection. The motors are adapted to voltage speed control in the range from 80 to 230V.
